The Opportunity
We are looking for a Finance Assistant to join our finance team with an immediate start. This is a great opportunity to gain hands-on experience in a high-growth deep-tech business, working across a defined set of transactional finance processes that are genuinely important to how we run day-to-day.
You'll be working as part of a team of four, picking up ownership of key tasks from day one — including expense management across our UK, US, and Singapore entities, and bank account reconciliations. This is ideal for someone with a finance interest who wants to consolidate their skills in a fast-paced environment, and who takes pride in getting things right.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You’ll Do
Expense management
- Reviewing and approving employee expense claims in line with company policy across the UK, US, and Singapore entities.
- Reconciling receipts to card transactions and following up on any missing documentation.
- Ensuring expenses are correctly coded and compliant before reaching payment stage.
Bank reconciliations
- Performing regular bank account reconciliations across multiple entities.
- Investigating and resolving discrepancies promptly and accurately.
- Keeping records clean and audit-ready at all times.
Ad hoc finance support
- Supporting the wider finance team with additional ad-hoc transactional tasks and process improvements as they arise.
What Makes a Great Candidate
- Switched-on and a fast learner — you pick things up quickly and don't need to be told the same thing twice.
- Highly organised, with a reliable approach to managing your own workload and deadlines.
- Accurate and detail-oriented — you take care to get things right and notice when something doesn't add up.
- A proactive communicator — you flag issues early and know when to escalate rather than sitting on a problem.
- Comfortable in a dynamic, fast-paced environment where you'll need to manage your time well.
